Answer:
yes
Explanation:
yes, because lets say you were a surgeon you would have sharp tools floating everywhere
Answer:
1). Brake pedal or lever
2). A pushrod also called an actuating rod
Answer:
218.5 N
Explanation:
In order for the sled to be in equilibrium along the vertical direction, the forces acting along this direction must be balanced. So the equilibrium equation is:
where
N is the normal force
F = 50 N is the force that pulls the sled
is the angle between the force and the horizontal, so
is the component of F acting along the vertical direction
(mg) is the weight of the sled, with
m = 25 kg being the mass of the sled
g = 9.8 m/s^2 is the acceleration due to gravity
Solving the formula for N, we find
Answer:
correct answers will be
2. The train is not an inertial frame of reference.
5.The train may be moving at a constant speed in a circle.
8. The train must be accelerating.
Explanation:
As we know that string makes an angle with the horizontal
so we can write the force equation for the given ball
also in Y direction
now we have
now we can conclude that train is accelerating with acceleration same as gravity
now correct answers will be
2. The train is not an inertial frame of reference.
5.The train may be moving at a constant speed in a circle.
8. The train must be accelerating.
The velocity will remain unchanged (Newton’s 1st Law) unless a force acts on it. If no friction force, then the velocity remains constant.
